New $100 bills are being introduced that host a variety of security features to make them harder to counterfeit. Paper is out. The bills are now made from a single piece of polymer, which makes the bill more durable and gives it a smooth texture, except for some key features that are raised. Within the transparent areas are complex holographic features, which can be viewed from both either side of the bill.

Scientists have succeeded in making the world's lightest material, so light it can float on top of dandeloin fluff, and they made it out of nickel. The metal used matters less than the structure. The material, developed by researchers at HRL Laboratories, LLC, is made out of micro-lattices that maximize strength in relation to the amount of material used. The structure is actually 99.99% air. Nickel was used by the researchers since it was the easiest material to work with.

(SAIL) and mineral giant NMDC Ltd. were leading the pack of overseas companies from Canada, US and Iran. A third Indian company, Ispat Alloys, was also included in the shortlist."

The Globe & Mail reports local authorities in the Pakistani province of Balochistan refused to meet Tethyan Copper, a joint venture between Chile’s Antofagasta and Barrick Gold, for talks before rejecting a bid for one of the world's richest deposits of gold and copper at a remote site in the dry hills near the Afghan-Pakistan border, known as Reko Diq. Tethyan Copper said a “summary decision” by the restive province to reject a mining lease application for its Reko Diq project breached local rules and Pakistani law and has now filed a "notice of dispute." The company submitted a feasibility study earlier this year that indicated 22 billion lb of copper and 13 million oz of gold at the site. The Balochistan decision now paves the way for a Chinese consortium to construct a mine and processing facility.

The continued surge in the gold price amid financial market turmoil is seeing a dramatic shift in the pattern of gold buying and selling at the world's central banks. The Globe and Mail reports that after two decades of being net sellers of gold, central banks are now buying gold at a record pace reflecting deep concerns about the viability of the US dollar and the euro as stores of value: Official net purchases of gold exploded in the third quarter, totalling 148.8 tonnes, more than double the entire amount of government buying in 2010, the World Gold Council, a London-based industry association, said in a new report Thursday. “We are seeing what now looks like unprecedented levels of central bank buying,” said Marcus Grubb, managing director, investment, at the Gold Council. “We do believe this is a long-term trend. This is not just short-term, tactical buying.”
